Differential cross sections and asymmetries at 90[degree] and 30[degree] are calculated for electron-hydrogen elastic scattering over the energies of the lowest [sup 1][ital S] and [sup 3][ital P] resonances using a nine-state coupled-channel calculation with and without continuum effects, which are represented by an equivalent local polarization potential. The polarization potential improves agreement with experiment in general for the spin-averaged cross sections. It is suggested that continuum effects would be critically tested by asymmetry measurements at 30[degree] over the [sup 1][ital S] resonance.
